Duodenal Switch has the highest rate of Type 2 Diabetes resolution of all weight loss surgeries available at this time. Duodenal Switch also significantly improves hyperlipidemia.Weight loss surgery has been shown to improve and in some cases resolved PCOS in general. A recent meta-analysis of the effects of bariatric surgery in more than 22,000 procedures found an average weight loss of 61%, associated with the complete resolution or improvement of diabetes, hyperlipidemia, hypertension, and obstructive sleep apnea in more than 60% of the patients. Another study looked just at PCOS patients and their metabolic improvement from 47% of the PCOS population to only 21% post Bariatric Surgery.
